A Novel Quantitive Calculation Method of Dynamic Misalignment in Rotor Systems

Chen Hong;Lei Wenping;Chen Lei;Han Jie;Zhengzhou University;  
The kinetic characteristics and motion forms of a twin-rotor system were analyzed from the kinetic point of view,and a novel quantitive calculation method of dynamic misalignment was proposed.The average shaft centerline positions were collected by eddy current transducers mounted on the rotor system,and translation displacements and angular displacements of shaft centerlines were calculated based on similar triangle theorem.Then according to vector synthesis principle,the amounts of the parallel misalignment and angular misalignment of the two rotors at the coupling were obtained.Engineering practices show that the calculation results are consistent with the typical features of the misalignment faults in time wave,spectrum and shaft centerline orbit.The forms and amounts of the misalignment faults might be obtained directly by this method.The novel method benefits the treatment of misalignment faults and shafting alignment in engineering practices.
